  • 3. Manufacturing System
    • Production is the process by Which goods
    • And services are created .
    • The conversion process can be categorise by the following activities
    • Receipt and storage of raw material
    • transportation
  • 4. Manufacturing System
    • 3 Inspection
    • 4 storage
    • It can be classified into two categories
    • Intermittent System
    • Continuous system
  • 5. Intermittent system
    • The goods are manufactured to fulfill orders made by customers rather than for stock.
    • Here flow of material is intermittent
    • Characteristics:-
    • 1. Most products are produced in small quantities
  • 6. Intermittent system
    • 2. Machines and equipment are laid out by process.
    • 3. Work loads are generally unbalanced.
